A 15,000 N crane can rotate around a frictionless shaft at its base and is supported by a cable that forms a 25-degree angle with the crane (see figure). The crane has 16 m long and not uniform; its center of gravity is 7.0 m from the shaft measured along the crane. The cable is subject to 3.0 m from the top end of the crane. The crane rises to 55 degrees above the horizontal, holding a container with 11,000 N bricks by a very light rope of 2.2 m. Calculate a) the voltage on the cable and b) the vertical and horizontal components of the force exerted by the shaft on the crane. Start by drawing a free body diagram of the crane.
